Swine flu, also known as the H1N1 virus, first was labeled as such in early 2009 with an outbreak in Mexico. Since then, it has swept across the world, prompting the World Health Organization (WHO) to declare a global pandemic. H1N1 has symptoms similar to regular influenza, yet H1N1 can be fatal, especially among those who already have medical problems. The U.S. Centers for Disease Control (CDC) has stated swine flu can be detected only by a test for it. The CDC states certain people are more susceptible to serious problems from H1N1, including the elderly, pregnant women, children 5 years old or younger and those with preexisting medical conditions, including respiratory maladies.
Respiratory
As with all varieties of influenza, swine flu can cause typical nasal problems, including nasal congestion and a runny nose. Although there is no cure for swine flu---it typically will go away on its own after it has run its course in three to seven days---you can take over-the-counter (OTC) drugs to help your nasal problems. For example, you can use allergy medications or nasal decongestants in pill, capsule or nasal spray form. Of particular danger is the H1N1 flu's effect on people who have asthma or other respiratory problems. Swine flu can exacerbate your symptoms and you may need a trip to the doctor or the emergency room for help.
Fever
A fever is a condition in which your body has a higher temperature than normal. Not everyone has a norm of 37 degrees C or 98.6 degrees F, so it is important to know your normal body temperature. A slightly higher temperature---99 or 100 degrees F or 37.5 degrees C---may be uncomfortable but is not generally serious. A fever is dangerous only when your temperature reaches 39.4 degrees C or 103 degrees F, according to the Mayo Clinic. Seek medical emergency help immediately if your temperature is that high. OTC drugs, including ibuprofen (Advil or Motrin), acetaminophen (Tylenol) or naproxen sodium (Aleve), can help you with minor fevers.
Other Symptoms
The H1N1 influenza also may cause other symptoms similar to common flu strains. These may include aches throughout the body, a headache, a sore throat and fatigue or general bodily weakness. According to the CDC, diarrhea and vomiting also may accompany swine flu. Again, these all may be mitigated to some degree with OTC allergy or cold and flu medications.
